This is a "SW" high drain battery. High Drain batteries are for applications
with a continuous, low power consumption and/or occasional high peak currents:
Analog and digital watches with extra functions (backlight, alarm), pocket
calculators, electronic games, cameras, etc. The 373, or SR916SW, is a popular
Silver-Oxide cell commonly used in watches, with a shelf life of 5+ years. The
high-drain equivalent of this cell, the 372 (or SR916W), may be substituted
for the low-drain 373 at no additional cost. Diameter: 9.5 mm. Height: 1.6 mm.
